From: Interfractional target changes in brain metastases during 13-fraction stereotactic radiotherapy

Definition Median period (days)

From CTS to the mid-treatment MRI scan 8 (range 6–17)
From the MRI scan before CTS to the mid-treatment MRI scan 14 (range 7–28)
From the MRI scan before CTS to SRT initiation 8 (range 3–21)
